Which statements about the modification of chromatin structure in eukaryotes are true? select all that apply. hints select all that apply. methylation of histone tails in chromatin can promote condensation of the chromatin. deacetylation of histone tails in chromatin loosens the association between nucleosomes and dna. dna is not transcribed when chromatin is packaged tightly in a condensed form. acetylation of histone tails in chromatin allows access to dna for transcription. some forms of chromatin modification can be passed on to future generations of cells. acetylation of histone tails is a reversible process?

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
